The Condes de Castro Guimarães is the grandest villa in Cascais. Situated on the edge of the Parque Marechal Carmona, its cheery yellow exterior features a neo-gothic tower and whimsical ornaments.

The villa was constructed in 1902 by Jorge O'Neil, an Irish tobacco millionaire, and the museum displays furniture and art from his personal collection. The highlight of the museum is a 16th-century manuscript that includes one of the oldest images of Lisbon.

To the north of Cascais is a jagged coastline of highly-weathered cliffs that are battered by the ferocious Atlantic Ocean.

The Boca do Inferno is a unique coastal feature - a sea cave that has collapsed, leaving just an arch in the rocks that was once the entrance to the cave. During winter storms, huge waves crash through the opening and spray is expelled upwards - however, it will be significantly less dramatic on a calm summer's day!

The Boca do Inferno is a pleasant 20-minute walk from the marina, and will make an interesting addition to your day trip.

The Praia da Rainha is a small but picturesque beach right in the centre of Cascais. The beach is so pretty that in 1889 it was chosen by Queen Amélia as her private beach, and has been known as the Praia da Rainha (Queen's Beach) ever since.

The Cabo da Roca headland is the most westerly point of mainland Europe, and is a barren, wind-swept landscape comprising of colossal cliffs and raging Atlantic waters. The main attraction of the Cabo da Roca is the raw beauty of nature, and is a magical location from which to watch the sun set over the vast Atlantic Ocean.

From the Cabo da Roca is a 2km coastal trail to the Praia da Ursa beach, one of the most beautiful beaches of the Lisbon region.

The Casa de Santa Maria was constructed as a wedding gift by Jorge O'Neil (who constructed the Condes de Castro) for his daughter. The house bucked the trends of the 1910s era, being constructed in a traditional Portuguese style using locally sourced materials.

Standing next to the Casa de Santa Maria is Cascais' lighthouse, with its unique quadrangular tower lined with blue and white tiles.

Praia do Guincho is a vast sandy beach that is exposed to strong prevailing winds and the huge waves of the Atlantic, making it ideal for surfing and kite surfing. Guincho beach is surrounded by the dramatic and unspoilt natural scenery of the Serra da Sintra, with its wind-swept hills and lush forests.

There is an 8km cycle path that connects Cascais to the Praia do Guincho. The path follows the rugged coastline and passes the Casa da Guia market, the Cabo Raso lighthouse and the Fortaleza do Guincho. As there are no hills along the route, hiring some bikes to cycle this path is an enjoyable half-day activity while on holiday to Cascais.

The Praia da Ursa is the most stunning of the beaches of the Serra de Sintra coastline, and the location to escape the tourist masses.

This remote beach sits at the base of a steep cliff, and is reached via dirt tracks and a footpath that scrambles down the side of the collapsed cliff. The Praia da Ursa is distinctive for its two huge rocky outcrops; sections of harder cliffs which have withstood the power of the Atlantic Ocean. These rocky islands give the beach its name as the ‘Rocha da Ursa’ supposedly looks like a bear (ursa in Portuguese)

Insight: There is a very scenic 1.7km coastal path from the Cabo da Roca to the Praia da Ursa, and this path is the suggestion to extend a visit to the Cabo da Roca.
